(1) technical field
The present invention relates to a kind of one-way belt sheave, particularly a kind of automobile current generator mono-directional overrun belt pulley.
(2) background technique
Development along with Hyundai Motor auto electronic and engine technique, automobile generating acc power improve constantly the lifting with rotating speed, for preventing that skidding from appearring in dynamo belt drive system, select suitable, the second best in quality mono-directional overrun belt pulley of function, for the electricity generate function of generator and belt life, reduce vibrations and lower oil consumption and there is greatest impact.Automobile current generator mono-directional overrun belt pulley mainly comprises that the parts such as band hub cap, mandrel and one-way mechanism and spring bearing form, when one-way mechanism and spring bearing all adopt needle roller, owing to axially cannot fixing and cause axial float, in running, axial movement value causes greatly vibrating greatly, noise is large.Spring bearing adopts the mode of interference fit to be arranged between belt wheel and mandrel, and the inconsistent meeting of magnitude of interference during spring bearing interference fit causes moving the disunity of transmitting torque.
Simultaneously existing automobile current generator mono-directional overrun belt sheave structure is complicated, manufacture cost is high, on general-utility car, can not apply widely.
(3) summary of the invention
The technical problem to be solved in the present invention is: adopt ball bearing and needle bearing as spring bearing, effectively control axial movement value, reduce vibration and noise.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automobile current generator mono-directional overrun belt pulley comprises that band hub cap (1), mandrel (2), Unidirectional combination hold (3), deep groove ball bearing (4), end cover (5), seal ring (6) and dust cover (7).
It is characterized in that: Unidirectional combination holds (3) outer ring and band hub cap interference fit, inner ring (3-2) and mandrel (2) external diameter close-fitting, while mandrel (2) one end close-fitting deep groove ball bearing (4), two ends are used respectively end cover (5) and seal ring (6) to carry out riveted and sealing, and dust cover (7) is equipped with in band hub cap one end.
The invention has the beneficial effects as follows: the present invention adopts a set of Unidirectional combination to hold and one-way mechanism and the supporting mechanism of deep groove ball bearing as main body, effectively control axial float in 0.1mm, improved the high speed running performance of bearing, band hub cap endoporus adopts hierarchic structure, be convenient to install that Unidirectional combination holds and deep groove ball bearing, assurance press-fits magnitude of interference, improves working life.That simultaneously the present invention has is rational in infrastructure, process the features such as easy, meets the real requirement of belt wheel of automobile engine.
